Optical Vibration

The vibration measurement is one of the new application in the optical sensor. This paper studies a new non-contact optical vibration sensor, and implements the Optical fiber vibration sensor based on FPGA. The totally available measurement range arrived over 300um, and the accuracy of 0.1 um can be obtained . This fiber optic vibration sensor has a low cost, good reliability, and high accuracy measurements.
